What is the gestation of rock wallaby?

There are many different species of wallaby but, on average, they have a gestation period of 30 days and spend 8-9 months in the pouch.

However, in reality, pregnancy length may differ. The mother wallaby may spend most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. This is called embryonic diapause.
